    摘要： The present invention relates to a mechanical fuse to seal pipes upon unintended rupture. When a pressure difference between a first pressure and a second pressure in a pipe is below a pressure threshold, a first spring retains a flap in a first position allowing gaseous fuel to flow from a first portion to a second portion and when the pressure difference between the first pressure and the second pressure is not below the pressure threshold the flap moves to a second position preventing the gaseous fuel from flowing from the first portion to the second portion.

    摘要： The present invention is related to a liquid blocking apparatus and a system thereof, wherein if the liquid contained in an IV bag or a liquid tank is oozed out completely, the flow of liquid is blocked, the alarm lamp is turned on, the alarm sound is generated, and then the supply of liquid is maintained for a predetermined time. A liquid blocking apparatus, or an IV set according to the present invention comprises an elastic support strip having a concave portion in a center thereof; an elastic operation strip having a convex portion in contact with said concave portion of said elastic support strip; and a housing including an inlet through which liquid is introduced, and an outlet from which liquid flows out are arranged at an upper and lower side thereof, wherein a pair of an elastic support strip and an elastic operation strip are mounted on one side thereof, and an alarm or a wireless calling device that transmits a wireless signal to the receiver of the integrated briefing room is mounted on the other side thereof, and a storage bag just below the housing. If the liquid is introduced, the convex portion of said elastic operation strip which is in contact with the concave portion of said elastic support strip is projected toward an opposing direction due to the water pressure, and the liquid can pass by, and if the liquid is not introduced, the convex portion of said elastic operation strip covers and blocks the outlet of said housing due to the force for restoring to an original form, and the liquid stored in the storage bag is supplied continuously for a predetermined time.

    摘要： A pool cleaner reed valve for a pulsating submersible swimming pool cleaner which has a valve body (22) configured to fit into a pulsating valve enclosure. The body includes a rectangular inlet end (24) and an round outlet end (26) with a pair of filcrum points (30) and restricting boundaries (32) for retaining and confining valve movements. A pair of opposed rigid valve plates (50) are angularly juxtaposed within the valve inlet end contiguously engaging the fulcrum points and respective restricting boundaries such that each opposed blade rotates inwardly on the fulcrum point until the distal ends intimately engage as influenced by negative fluid pressure applied by a pool pump. A pair of torsion springs (70) surround each restricting boundary and interface with each valve plate returning them to a parallel position when fluid pressure is terminated. A resilient sleeve (72) is positioned on each spring for eliminating a metal to metal contact with the spring to the valve plate.

    摘要： The present invention is directed to a multi-cuspid back-flow preventer in the nature of a check valve that has a generally annular body portion with axially spaced upstream and downstream ends. A substantially cylindrical passageway extends through the body portion, and a plurality of circumferentially adjacent valve cuspids are connected to the downstream end of the body portion for selectively opening and closing the passageway that extends therethrough. Each valve cuspid is marginated by a rib that extends into the passageway. Breather slots are provided between the successively adjacent valve cuspids, and a mounting flange may be provided at the upstream end of the body portion.
